Lecture 9 - Scattering and tunneling for a delta
... Notice that if the sign of is reversed, i.e. we have a potential barrier instead of a well, the reflection and transmission coefficients are unchanged. Even if the potential is much larger than E there is a non-zero probability that the particle can cross the potential barrier. This is the effec ...

Simple, accurate electrostatics-based formulas for calculating
... Above, Eq. (4b) is a simplification of the result of a power series expansion of Eq. (4a) taken through second order in /Rn . While these equations are classical in their overall form, the distance is quantum mechanical in its origin, as we have noted above. Thus, the addition of this finite distanc ...

Lagrange`s and Hamilton`s Equations
... We now apply the notion of the Legendre transform to the classical Lagrangian. In our previous developments, we have taken L to be a function of all the generalized coordinates and their respective time derivatives; i.e. L = L({qi }, {q̇i }, t). For generality, we have also included the possibility ...

Probability in the Many-Worlds Interpretation of Quantum Mechanics
... pyes = 13 = ⟨PA ⟩. Now we can add to the MWI the locality and causality postulates. The MWI yields: There is nothing but the wave function. Locality provides: Outcomes of local experiments depend only on local values of the wave function. Causality of relativistic quantum theory yields: Any action i ...
